The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
The shape of the plot reveals the degree and nature of hearing loss, distinguishing conductive hearing loss from other kinds of hearing loss. A conductive hearing loss is characterized by a difference of at least 15 decibels between the air conduction threshold and bone conduction threshold at the same frequency. On an audiogram, the "x ...
Here's how to read an audiogram and a doctor's explanation of the most common results including sloping hearing loss, notched hearing loss, cookie-bite hearing loss and reverse-sloping hearing loss.
The shape of the audiogram resulting from pure-tone audiometry gives an indication of the type of hearing loss as well as possible causes. Conductive hearing loss due to disorders of the middle ear shows as a flat increase in thresholds across the frequency range. Sensorineural hearing loss will have a contoured shape depending on the cause ...
Sensorineural hearing loss: Conductive hearing loss: Anatomical site: Inner ear, cranial nerve VIII, or central processing centers Middle ear (ossicular chain), tympanic membrane, or external ear: Weber test: Sound localizes to normal ear in unilateral SNHL Sound localizes to affected ear (ear with conductive loss) in unilateral cases Rinne test
A complete hearing evaluation involves several other tests as well. [5] In order to determine what kind of hearing loss is present, a bone conduction hearing test is administered. In this test, a vibrating tuning fork is placed behind the ear, on the mastoid process. When the patient can no longer feel/hear the vibration, the tuning fork is ...
A Rinne test should always be accompanied by a Weber test to also detect sensorineural hearing loss and thus confirm the nature of hearing loss. The Rinne test was named after German otologist Heinrich Adolf Rinne (1819–1868); [ 3 ] [ 4 ] the Weber test was named after Ernst Heinrich Weber (1795–1878).
Mixed hearing loss is a combination of conductive and sensorineural hearing loss. Chronic ear infection (a fairly common diagnosis) can cause a defective ear drum or middle-ear ossicle damages, or both. In addition to the conductive loss, a sensory component may be present.
